Patna: After taking over as chief minister again, Nitish Kumar on Thursday thanked Prime Minister Narendra Modi for his greetings and said he has faith that with the central government's assistance, development would gain pace in Bihar.

"Thankful to Prime Minister for his greetings. No compromise will be done on corruption. I have faith that with Centre's assistance development would get pace," the JD-U chief said in a tweet.

The Janata Dal (United) chief's remarks came after Modi greeted him shortly after he took oath with the BJP as an alliance partner in the state.

In a tweet, Modi said he was looking forward to working together with Nitish Kumar for Bihar's progress.

Nitish Kumar unexpectedly resigned on Wednesday, but hours later joined hands with the BJP to reclaim the government in a stunning political manoeuvre that relegated his alliance partner RJD to the Opposition.

The ostensible reason for Kumar to quit was his falling out with Deputy Chief Minister Tejashwi Yadav, the son of RJD supremo Lalu Prasad. Yadav is facing corruption charges but had refused to step down despite Kumar's exhortations.
